I am trying to get a Z-5450 sub to work and if possible the left and right channels. I have seen the pinout for the Z-5500, what I would like to know is if anyone has a pinout for the Z5450 and If it is the same? I read camouflageX 's post but you don't mention the other connections for FL FR nor if you got it to work!

Any help on this would be great I can start messing about but it would be nice to get as much info as possible.

There are, or were, some relatively inexpensive Dolby Digital decoders out there that were intended for computer sound, but for some reason they're fetching silly amounts of money on eBay, last time I checked. Creative's DDTS-100 is one; there's others, some very obscure. Possibly the best bet is the original Creative Labs Extigy; it is supposed to work in standalone mode (not plugged into a computer via USB) as a DD decoder. Those don't fetch much money on the 'bay, and don't take up much space.

For reasons I don't understand, Dolby Digital doesn't seem to have been a success in the car video market, so you may find deals on 12V Dolby Digital decoders. I've picked up two Panasonic units from the clearance table at a local store for $25 each. CY-AC300EX, or something like that; they have a wired control/display unit, but tragically no wireless remote for volume. Be careful with other autosound DD decoders, since some only work with particular head units.

Finally, there were various add-on surround decoders intended for use with AV receivers that were sold as "digital ready" (meaning they had 5.1 analog inputs). Most were Dolby Digital only, but the Technics SHAC-500D included DTS, and included a remote for volume control and source switching, which made it a very usable if you hooked it up to separate power amps. Stereophile's Guide To Home Theater gave the Technics receiver/decoder combo a class B rating, which is rather high praise for a setup you could buy at a big box store. Keep your eyes open at pawn shops, yard sales and the trade-in shelves at audio boutiques.

However, for the same kind of money you ought to be able to find an entry level digital surround A/V receiver. I'd expect demand (and prices) for Dolby Digital/DTS surround stuff should be way down now that HDMI audio is the state of the art.

it's good to see that you are also trying to get the Z-5450 to work. Maybe we can join forces. Well yes, I got the front speakers to work although they are very loud, so keep the volume down or use a high ohm resistor.

This is my current understanding of the Z-5450 connector at the moment:

A connection for the speakers to a 3,5 mm jack would look like this:
pin 5 <--- line out tip (audio for left speaker)
pin 6 <--- line out GND (unmute left, right, subwoofer)
pin 7 <--- line out GND (turns amp on)
pin 8 <--- line out GND (unmute center (optional))
pin 9 <--- line out ring (audio for right speaker)
pin 13 <--- line out GND (signal GND)

OK guys, finally... After some really long nights I was able to get the correct wire configuration by tracing the boards and doing some research on the chips. I still have a problem, but first I will give you my results, maybe somebody will find them useful:

Now, on to my problem. So after I have the control pod connected, I still don't get a decent subwoofer volume. I can barely hear it when I turn the volume all the way up. When I connect the subwoofer driver wires (red and black) directly to an amped output, it works just fine, so that part is OK. BTW, the satellites work without any problems.

I have Logitech Z-5300e Speakers and i lost the Wired Remote (SoundTouch) and i want to use it without remote but i cant because the power switch is located on remote which is directly connected to the SUB.

well it looks like the Z-5300 uses the control pod in a totally different way than the Z-5400 and Z-5500 series. As far as I see the pod on the Z-5300 only controls ON/OFF, volumes and things like that. So at least you'll have to find a way to turn the system on and set a high volume level. According to the information in another forum it uses digital TTL signals for the volume controls, which are hard to replicate yourself. That's a shame, because you can't just take the information we already have for our systems and just copy it.

There would also be way to bypass the digital audio controlling so that you don't have wo worry about the volume control, but it won't be easy either. Basically you'll have to skip the digital audio processor which is inside the back of the subwoofer. So you hook up your analog audio behind the digital audio processor and let it continue from there. But if you are really lucky this isn't even needed, because it already has a default volume. I don't know about that...

Unfortunately I can't get into details about the Z-5300, because I don't have any experience with that system. The best would be to ask Koryo in the other forum, because he seems to have much knowledge about it. Good luck!
